Construction box system for a 3D printer, 3D printer, 3D printer system,
use of the construction box system, and 3D printing method
The present invention relates to a construction box system for a 3D printer, a
3D printer comprising the construction box system, a 3D printer system
5 comprising the 3D printer, a use of the construction box system, and a 3D
printing method.
Various generative manufacturing processes and 3D printing processes (and
consequently various types of 3D printers, i.e. machines/constructions for
10 building up a component in layers) are known.
Some generative manufacturing processes have the following steps in common:
(1) First, particulate material (and particulate construction material,
respectively)
is applied over the entire surface of/continuously on a construction field, so
as
15 to form a layer of unsolidified particulate material.
(2) The applied layer of unsolidified particulate material is selectively
solidified in
a predetermined partial area (In accordance with the component part to be
manufactured), for example by selectively printing a treatment agent, for
example a binder, alternatively, for example, by laser sintering.
zo (3) Steps (1) and (2) are repeated to manufacture a desired component.
For this
purpose, a construction platform on which the component is built up in layers
may, for example, be lowered by respectively one layer thickness before a new
layer is applied (alternatively, the coater and the printing device may, for
example, be raised by respectively one layer thickness).
25 (4) Finally, the manufactured component which is formed by the
solidified partial
areas and is supported and surrounded by loose, unsolidified particulate
material may be unpacked.
The construction space in which the component or the components is/are
30 manufactured may, for example, be defined by a so-called construction
box
(also referred to as "job box" or "swap container"). A construction box of
this
type may have a circumferential wall structure which is open in an upward
direction and extends in a vertical direction (for example formed by four
vertical
CA 03134375 2021- 10-20
2
side walls), which may, for example, be formed to be rectangular when viewed
from above. A height-adjustable construction platform may be received in the
construction box. In this respect, the space above the construction platform
and
between the vertical circumferential wall structure may for example at least
5 contribute to forming the construction space. An upper area of the
construction
space may, for example, be referred to as a construction field. An example of
a
construction box is, for example, described in DE 10 2009 056 696 Al. Another
example of a construction box is, for example, described in DE 20 2006 010
327 Ul.
A coater (also referred to as a "recoater") is normally used in the above step
(1).
Various coaters are known for use in 3D printers, by means of which a
particulate construction material may be applied to the construction field
(also
referred to as construction surface or construction area) in the form of a
uniform
15 layer over the entire surface/a continuous layer.
One type of coater uses a roller (short: "roller coater") in front of which
first an
amount of particulate construction material is put down and which is then
horizontally moved across the construction field to apply the particulate
20 construction material in the form of a uniform layer onto the
construction field. In
this respect, the roller may be rotated opposite to the moving direction.
Another kind of coater (a so-called ucontainer coater, for example a "slot
coater") uses a container which defines an inner cavity for receiving
particulate
25 construction material, and has an (for example elongate) output region,
for
example comprising an (for example elongate) output slot, for outputting the
particulate construction material. The container coater may, for example, be
movable across a/the construction field (for example horizontally, for example
transverse to its longitudinal direction), wherein the particulate material
can be
30 output onto the construction field through the (elongate) output region
to thereby
apply a uniform construction material layer continuously / over the entire
surface
of the construction field and the construction platform, respectively. The
coater
may be elongate, for example, to span or to cover the length or width of a
rectangular construction field or construction space.
CA 03134375 2021- 10-20

In the above step (2), a printing device having a print head may for example
be
used, which applies a treatment agent in a controlled way onto a partial area
of
a/the particulate material layer applied before (so-called binder jetting).
The
5 treatment agent contributes to a (direct and/or later) solidification of
the
construction material layer in the partial area. For example, the treatment
agent
may be/contain a binding agent, for example binder, for example a binder
component of a multicomponent binder.
10 Alternatively, a laser may, for example, be used in the above step (2)
to solidify
a partial area of the construction material layer applied previously, in
particular
by sintering or melting the particulate material in the partial area.
It may be regarded as an object of the present invention to provide a
15 construction box system for a 30 printer and a 30 printing method by
which a
component can be efficiently manufactured by 3D printing.
To this end, the present invention provides a construction box system for a 3D
printer according to claim 1, a 3D printer according to claim 12, a 3D printer
zo system according to claim 13, a use of the construction box system
according to
claim 14, and a 3D printing method according to claim 15.
According to various aspects of the invention, a construction box system for a
3D printer comprises a construction box having a side wall structure (for
25 example, a construction box side wall structure) and a construction
platform
received within the side wall structure, the side wall structure defining an
upwardly open construction box interior space (for example, construction
space)
for building a component (for example, at least one component, for example,
one or more components) in 3D printing (for example, by means of a 3D printing
30 method) which is downwardly delimited by the construction platform, and
a
support structure comprising its own drive integrated into the support
structure
and to which the construction box is releasably (for example repeatedly, for
example multiple times) attachable (for example fixable, for example attached,
for example fixed) so that the construction box can be repeatedly removed (for
CA 03134375 2021- 10-20
4
example detached and removed) from the support structure after building the
component in the construction box interior space and subsequently reattached
(for example fixed, for example attached and fixed) to the support structure.
5 Since the construction box is detachable from the support structure, the
construction box can be fed, for example separately from the support
structure,
to a process following the 3D printing (so-called post-process), such as an
unpacking and/or curing and/or drying of the component produced in the
construction box. Meanwhile, another construction box can be arranged on the
10 support structure, for example, so that 3D printing can be performed or
a
component can be built up in 3D printing in the other construction box, for
example, in parallel/simultaneously with the post-process performed in one
construction box. This enables, for example, low idle times of the individual
components of the construction box system (such as the construction box(es)
15 and/or the support structure). Since the support structure has its own
drive
integrated into the support structure, the construction box can, for example,
be
configured free of a drive means (i.e., without its own drive integrated into
the
construction box). This enables, for example, a simple and cost-effective
assembly of the (for example respective) construction box, while nevertheless
zo enabling simple handling of the construction box by means of the (for
example
common) support structure. In addition, the construction box can then be made
accessible to, for example, post-processes of the type having conditions that
are detrimental to the support structure and its drive. Thus, the construction
box
system enables, for example, an efficient implementation of 3D printing
25 processes and/or an efficient production of 3D printed components and/or
an
efficient operation of a 3D printer or a 3D printer system.
For example, the side wall structure of the construction box may have at least
one side wall (for example, four side walls). For example, the side wall
structure
30 of the construction box may be formed by four side walls (for example,
construction box side walls). The construction box side wall structure (for
example, the four construction box side walls) may have, for example, a
rectangular shape in a plan view, for example comprising two long and two
short sides.
CA 03134375 2021- 10-20

The drive integrated into the support structure may comprise, for example, a
lift
drive (for example, a construction platform lift drive) for adjusting the
height of
the construction platform, configured to adjust the construction platform of
the
5 construction box in height when the construction box is attached to the
support
structure.
With a/the lift drive integrated into the support structure, the construction
platform can be moved, for example, in a controlled and automated manner
10 between an uppermost position, in which the construction platform is
arranged
at the beginning of a/the 3D printing process, and a lowermost position, in
which
the construction platform is held by a/the holding structure (for example, the
holding structure described below) (and in which the construction platform is
arranged, for example, at the end of a/the 3D printing process). For this
15 purpose, the lift drive may, for example, be coupled or connected to a
control
device (for example, a central control device of the 3D printer, for example,
a
control device integrated into the support structure). A device integrated
into the
construction box for adjusting the height of the construction platform may
therefore be omitted. A device integrated into the 3D printer or provided on
the
zo 3D printer for adjusting the height of the construction platform may
also be
omitted.
The drive integrated in the support structure may, for example, comprise a
travel drive (for example, a support structure travel drive) for moving the
support
25 structure, which is configured to move the construction box system (for
example, the support structure with the construction box arranged thereon)
between a first position (for example, a build position), in which the
construction
box system is arranged in the 3D printer for building up the component, and a
second position in which the construction box system is arranged, for example,
30 outside the 3D printer, for example along a rail system or a roller
system
extending between the first position and the second position.
With a/the travel drive integrated into the support structure, the
construction box
system may be moved between the first position and the second position, for
CA 03134375 2021- 10-20
6
example, in a controlled and automated manner. For this purpose, the travel
drive may, for example, be coupled or connected to a/the control device (for
example, a/the central control device of the 3D printer, for example, a/the
control device integrated into the support structure). A separate device for
5 moving the construction box system or the support structure may therefore
be
omitted. A device integrated into the 3D printer or provided on the 3D printer
for
moving the construction box system or the support structure may also be
omitted.
10 The second position may be, for example, a position for detaching (and,
for
example, removing) a/the construction box from the support structure andlor
attaching (and, for example, fixing) it to the support structure. The second
position may be, for example, a position for detaching and removing a/the
construction box from the support structure and/or for attaching a/the
15 construction box to the support structure and/or for changing or
replacing a/the
construction box on the support structure. The second position may be, for
example, a construction box change position and/or a construction box
exchange position.
zo If the travel drive and/or the lift drive are integrated into the
support structure of
the construction box system, corresponding devices of the 3D printer for
height
adjustment of the construction platform and/or for moving the support
structure
and/or the construction box system between a/the first position and a/the
second position, for example, may be omitted. This can, for example, simplify
25 the assembly of the 3D printer. In addition, for example, maintenance
work on
the travel drive and/or lift drive can be carried out easily and at low cost
outside
the 3D printer, while the 3D printer may meanwhile continue to be operated,
for
example, with another construction box system.
30 The travel drive and/or the lift drive may, for example, each be
configured as at
least one electric motor. For example, several electric motors may be provided
in each case as the travel drive and/or as the lift drive, which are
controlled for
synchronous operation or are coupled to one another. The travel drive may, for
example, be formed by one electric motor and the lift drive may, for example,
be
CA 03134375 2021- 10-20
7
formed by two electric motors synchronized with one another. The travel drive
and/or the lift drive may, for example, have a vertical drive axis.
The support structure may be electrically connected, for example, via a
trailing
5 or rolling cable chain, to the 3D printer, for example, to a/the central
control
device of the 3D printer, which may be configured, among other things, to
control the travel drive and/or the lift drive, and/or to a central power
supply of
the 3D printer. For controlling the travel drive and/or the lift drive,
however, the
support structure may, for example, also comprise a control device integrated
10 into or arranged on the support structure. For the power supply of the
travel
drive and/or the lift drive, the support structure may, for example, also be
formed with an accumulator or comprise an accumulator.
The lift drive may, for example, be configured to drive at least one (for
example,
15 two) spindle drives arranged on the support structure. The lift drive
may, for
example, drive at least one (for example, two) spindle drive(s) arranged on
the
support structure. For example, the support structure may include at least one
(for example, two) spindle drive(s) attached to the support structure and
drivable or driven by the lift drive. The spindle drive (for example, each of
the
zo two spindle drives) may comprise, for example, a (for example,
rotatable) screw
spindle and a spindle nut. The spindle drive or screw spindle may be rotatably
disposed, for example, adjacent to a support structure side wall structure and
a
support structure side wall, respectively. The screw spindle may, for example,
be connected to the lift drive (for example fixedly, for example releasably,
for
25 example by means of a coupling). For example, two electric motors may be
provided as the lift drive, each of which drives a spindle drive, wherein each
spindle drive comprises, for example, a rotatable screw spindle and a spindle
nut, and wherein the two spindle drives are arranged, for example, adjacent to
opposite support structure side walls. The spindle drive or rotatable screw
30 spindle may comprise, for example, a vertical axis of rotation.
The travel drive may, for example, be configured to drive at least one gear
wheel fixed to the support structure. For example, the travel drive may drive
at
least one gear wheel fixed to the support structure. For example, the support
CA 03134375 2021- 10-20
8
structure may comprise at least one gear wheel attached to the support
structure, which is drivable or driven by the travel drive. For example, the
gear
wheel may be connected to the travel drive (for example fixedly, for example
releasably, for example by means of a coupling). The gear wheel may be
5 attached, for example, to the lower side of the support structure. The
gear
wheel may be attached, for example, to an outer side of the support structure,
for example, in a lower region of the outer side. The gear wheel may comprise,
for example, a vertical wheel plane or a horizontal wheel plane. The gear
wheel
may be, for example, a vertical gear wheel or a horizontal gear wheel. For
10 example, there may be several gear wheels attached to the support
structure,
which are driven by a common electric motor via a gearbox or by synchronously
running separate electric motors. The gear wheel fixed to the support
structure
may, for example, cooperate with a rack. For this purpose, the gear wheel may,
for example, engage the rack and roll on the rack when driven by the travel
15 drive, so that the construction box system is movable along the rack.
The rack
may, for example, comprise a lateral tooth surface in which a gear wheel with
a
horizontal wheel plane engages laterally. The rack may be arranged, for
example, between two rolling or sliding rails, for example adjacent to one of
the
two rolling or sliding rails, of a/the rail system along which the support
structure
20 may slide/roll with skids. Alternatively, the rack may be formed, for
example, by
one of the two rolling or sliding rails on which the support structure stands,
for
which purpose the side surface of the rolling or sliding rail is provided with
teeth.
The lift drive and/or the travel drive and/or the spindle drive may, for
example,
25 be arranged outside the side wall structure of the construction box when
the
construction box is attached to the support structure, for example as seen
from
above in a top view of the construction box system next to the construction
box
adjacent to the side wall structure of the construction box and/or adjacent to
at
least one side wall of the support structure, for example in the case of an
30 elongated construction box in the longitudinal direction in front of
and/or behind
the side wall structure of the construction box and/or in front of and/or
behind at
least one side wall of the support structure. As a result, the construction
box
system may be designed, for example, with a low height and thus in a way to be
CA 03134375 2021- 10-20
9
compact. Furthermore, for example, the lift drive and/or the travel drive
and/or
the spindle drive may be easily accessible.
For example, the support structure may be formed to be elongated and the lift
5 drive and/or the travel drive and/or the spindle drive may be arranged,
for
example, at at least a longitudinal end of the support structure. For example,
the
travel drive may be arranged at a first longitudinal end of the support
structure
and the lift drive may be arranged at the first and at a second longitudinal
end of
the support structure. As a result, the construction box system may, for
10 example, have a low height and thus be formed to be compact.
Furthermore, for
example, the lift drive and/or the travel drive and/or the spindle drive may
be
easily accessible.
The construction platform may, for example, be engaged from below/reached
15 under by one or more support structures (for example adjustable in a
vertical
direction or height direction), for example one or more support arms (for
example comprising an L-structure), which are connected to the lift drive (for
example fixedly, for example releasably, for example by means of a coupling)
and can be driven by it when the construction box is attached to the support
zo structure. In the side wall structure of the construction box and/or in
a support
structure side wall structure, for example, one or more slots (for example
longitudinal slots extending in a height direction) may be formed through
which
the one or more support structures extend. The slots may extend, for example,
from a lower end (for example, a lower edge) of the support structure side
wall
25 structure or the construction box side wall structure in an upward
direction (for
example, vertically upward). For example, the slots may be configured (for
example, have an extension (for example, length) in the height direction (or
vertical) direction)) such that the construction platform is movable between a
lowermost position where the construction platform is held by a holding
30 structure (for example, the holding structure described below) and an
uppermost position where a floor (for example, an upper part or upper portion,
for example, a work surface) of the construction platform is arranged
substantially level with an upper edge of the construction box side wall
structure
(and in which the construction platform is arranged at the beginning of a/the
3D
CA 03134375 2021- 10-20
10
printing process). For example, the support structure may be connected to the
spindle nut (for example, fixedly, for example, releasably), for example, via
a
support structure fastening member to which the support structure is fastened
and which is connected to the spindle nut (for example, fixedly, for example,
5 releasably). In this way, for example, a safe and reliable height
adjustment of
the construction platform can be achieved. In addition, the construction box
system can thereby be designed to be compact and reliable, for example.
The one or more support structures may, for example, be adjustable or adjusted
10 in a height direction (or vertical direction) by means of the lift
drive. The one or
more support structures may, for example, each extend through an associated
slot in the support structure side wall structure, for example through an
associated slot in a support structure side wall, for example towards an
opposite
support structure side wall. The one or more support structures may, for
15 example, be configured to releasably contact the construction platform
when the
construction box is attached to the support structure, for example such that
the
construction platform is height-adjustable by a vertical movement (or a
movement in a height direction) of the support structures.
zo For example, the lift drive and/or the travel drive and/or the spindle
drive may be
disposed in a space formed between a support structure side wall and a
cladding wall of the support structure. Thereby, for example, the lift drive
and/or
the travel drive and/or the spindle drive can be easily accessible.
25 For example, the support structure may comprise a support structure side
wall
structure that surrounds the side wall structure of the construction box in
the
circumferential direction at least in sections, for example surrounds it at
both
end faces of an elongated construction box, for example completely surrounds
it
at both end faces of an elongated construction box, for example when the
30 construction box is attached to the support structure. The support
structure side
wall structure may, for example, be formed in a shape corresponding to the
side
wall structure of the construction box. For example, the support structure
side
wall structure may be complementary in shape to the side wall structure of the
construction box. For example, the support structure side wall structure may
CA 03134375 2021- 10-20
11
have at least one support structure side wall (for example, two support
structure
side walls). Thereby, for example, an easy attachment of the construction box
to
the support structure and/or easy removal of the construction box from the
support structure may be achieved.
For example, the support structure and/or the support structure side wall
structure may have two opposing support structure side walls between which
the construction box is attachable, for example such that portions of the side
wall structure of the construction box (for example, two short construction
box
side walls) are disposed adjacent to the support structure side walls (for
example, to portions of the support structure side walls) (for example, at a
distance of 5 cm or less, for example, 3 cm or less, for example, 1 cm or
less),
for example, when the construction box is attached to the support structure.
Thereby, for example, easy attachment of the construction box to the support
structure and/or easy removal of the construction box from the support
structure
can be achieved. The drive (for example the lift drive and/or the travel
drive)
may, for example, be arranged adjacent to at least one of the two support
structure side walls on a side of the support structure side wall facing away
from
the construction box.
The support structure side wall structure may, for example, surround the side
wall structure of the construction box in a circumferential direction in
sections
(for example, when the construction box is attached to the support structure),
thereby forming at least one recess. The recess may be dimensioned, for
example, such that the construction box may be laterally removed from the
support structure and/or reattached to the support structure, for example,
through the recess. The support structure side wall structure may, for
example,
comprise two opposed recesses, each of which may, for example, be
dimensioned such that the construction box may, for example, be laterally
removed from the support structure and/or reattached to the support structure
through the respective recess. The at least one (for example both) recess may
for example extend along a (respective) long side of the side wall structure
of
the construction box. Thereby, for example, easy attachment of the
construction
CA 03134375 2021- 10-20
12
box to the support structure and/or easy removal of the construction box from
the support structure may be achieved.
The support structure side wall structure may, for example, comprise several
5 (for example, two) support structure side walls or may be at least co-
formed (for
example, formed) by these. The support structure may be formed to be
elongated, for example. For example, the support structure may be formed to
be rectangular in a plan view, for example having two short and two long
sides.
The support structure or the support structure side wall structure may
comprise,
10 for example, two support structure side walls arranged (for example in a
longitudinal direction) in front of and behind the construction box (for
example,
adjacent to the side wall structure of the construction box, for example,
adjacent
to the short sides of the construction box) when the construction box is
arranged on the support structure. The support structure or the support
15 structure side wall structure may comprise, for example, a first support
structure
side wall and a second support structure side wall, the first support
structure
side wall being arranged (for example in a longitudinal direction) in front of
the
construction box (for example, adjacent to a first portion of the construction
box
side wall structure, for example adjacent to a first short side of the
construction
zo box) and the second support structure side wall being disposed (for
example in
a longitudinal direction) behind the construction box (for example adjacent to
a
second portion of the construction box side wall structure, for example
adjacent
to a second short side of the construction box) when the construction box is
disposed on the support structure. The lift drive andlor the travel drive
and/or
25 the spindle drive may be arranged, for example, adjacent to at least one
support
structure side wall (for example, both support structure side walls), for
example,
when the construction box is arranged on the support structure, on a side of a
(respective) support structure side wall facing away from the construction
box.
30 For example, when the construction box is arranged on the support
structure,
the construction box may, for example, be supported by the support structure
such that an upper edge of the side wall structure of the construction box is
arranged substantially at the same height as an upper edge of the support
structure side wall structure.
CA 03134375 2021- 10-20
13
For example, the support structure may comprise at least one (for example,
two) construction box support member for supporting the construction box when
the construction box is disposed on the support structure. The at least one
5 construction box support member may be arranged, for example, below the
construction box when the construction box is arranged on the support
structure. The at least one construction box support member may be at least
co-formed, for example formed, by the support structure side wall structure
(for
example by the support structure side wall(s)). The at least one construction
10 box support member may be attached, for example, to the support
structure
side wall structure (for example, to the support structure side wall(s)), for
example, a support member may be attached to each of the two support
structure side walls disposed (for example in a longitudinal direction) in
front of
and behind the construction box when the construction box is disposed on the
15 support structure. For example, the support structure may comprise two
opposed construction box support members. The two opposing construction
box support members may, for example, each extend between the two support
structure side walls and have a lower height (for example, lower extension in
the vertical direction) than the support structure side walls. The two
opposing
zo construction box support members may, for example, be arranged on
opposing
support structure side walls.
The support structure may for example comprise two (for example opposing)
support structure side walls and two (for example opposing) construction box
25 support members, wherein for example the two support structure side
walls are
arranged in front of and behind the (for example elongated) construction box
and/or the two support structure side walls are arranged adjacent to the side
wall structure (for example to portions thereof, for example to the short
sides) of
the construction box when the construction box is arranged on the support
30 structure, and wherein for example the two construction box support
members
are arranged such that the construction box is supported by the two
construction box support members when the construction box is arranged on
the support structure. Thereby, for example, easy attachment of the
CA 03134375 2021- 10-20
14
construction box to the support structure and/or easy removal of the
construction box from the support structure may be achieved.
For example, the one or more support structures may have a lower height (for
5 example, lower extension in the vertical direction) than the construction
box
support members when the support structures are in the lowermost position.
Thereby, for example, easy attachment of the construction box to the support
structure and/or easy removal of the construction box from the support
structure
may be achieved.
The support structure may, for example, comprise a construction box fixing
device by means of which the construction box releasably attached to the
support structure may be fixed, for example such that the construction box
(for
example the construction box side wall structure) is stably (for example in a
15 fixed way, for example immovably) held in a desired position. For
example, the
construction box fixing device may comprise at least one bolt (for example,
two
or four bolts) configured to engage a bolt receiving opening provided on the
construction box. For example, the construction box may be fixed in a first
horizontal direction (for example, the first horizontal direction may be a
zo longitudinal direction of an elongated construction box or an elongated
support
structure) by the support structure side wall structure (for example, by two
support structure side walls) and fixed in a second horizontal direction
perpendicular to the first horizontal direction by the construction box fixing
device.
The support structure may, for example, comprise lateral guide rollers. The
guide rollers may, for example, be attached to the lower side of the support
structure. The guide rollers may be attached, for example, to the outer side
of
the support structure, for example in a lower region of the outer side. The
guide
30 rollers may have, for example, a vertical rolling axis. The guide
rollers attached
to the support structure may, for example, cooperate with two guide rails on
which the guide rollers roll. One of the two guide rails may, for example, be
formed by the rack, i.e. by the side surface of the rack which is opposite the
tooth surface, for example by the outer side surface of the rack, the inner
side
CA 03134375 2021- 10-20
15
surface of the rack being formed as the tooth surface. For example, the other
guide rail may be formed by one of the two rolling or sliding rails mentioned
above, for example by an inner side surface of the rail. For example, however,
both guide rails may also be formed by the rolling or sliding rails, or two
5 separate guide rails may be provided. The lateral guide rollers can be
used, for
example, to center the support structure along a horizontal direction
perpendicular to the direction of travel, so that the construction box system
can
be moved specifically to the first position. Separate centering/fixing of the
construction box system in the first position along the horizontal direction
10 perpendicular to the direction of travel can thus be omitted.
The support structure may, for example, comprise two or more skids with which
the support structure rests in a sliding manner on corresponding rails of a
rail
system. The rails of the rail system may, for example, be rolling rails, i.e.
15 comprise rollers on which the skids roll. Alternatively, the rails of
the rail system
may also be sliding rails, i.e. comprise sliding surfaces on which the skids
slide.
For example, the support structure may comprise a tapered alignment recess,
for example a cone-shaped recess. The 3D printer (for example, a frame
zo thereof) may have attached thereto, for example, an alignment member
that is
horizontally adjustable perpendicular to the direction of travel of the
construction
box system, the alignment member comprising a tapered end portion (for
example, an alignment mandrel, for example, a cone-shaped mandrel) that
laterally engages the alignment recess in the first position of the
construction
25 box system. The alignment recess of the support structure and the
adjustable
alignment member of the 3D printer together form a construction box system
fixation system for aligning the construction box system along the
construction
box system travel direction and for fixing the construction box system in the
3D
printer (for example, to the frame thereof). In addition, the construction box
30 system fixation system may, for example, comprise a fixing member (for
example, a bolt) arranged on the 3D printer (for example, on its frame) and
having a flat-shaped end portion that is adjustably pressable against a stop
plate attached to the support structure. For example, a rail on the opposite
side
of the support structure may serve as an abutment. Furthermore, the
CA 03134375 2021- 10-20
16
construction box system fixation system may, for example, comprise a sensor
for determining the position of the construction box system, in particular
whether
the construction box system is in the first position. For this purpose, a
sensor
target may be attached to the support structure, for example. Furthermore, the
5 construction box system fixation system may, for example, comprise a
control
system that controls a drive of the alignment member and the fixing member
such that the alignment member moves into the alignment recess and the fixing
member is pressed against the stop plate when the sensor detects that the
construction box system is in the first position.
The construction box may have, for example, a rectangular shape in a plan
view, with two opposing short construction box side walls and two opposing
long construction box side walls. For example, the construction box may have a
length of 1.2 m or more (for example, 1.3 m or more, for example, 1.4 m or
15 more, for example, 1.5 m or more) and 2.0 m or less (for example, 1.9 m
or
less, for example, 1.8 m or less, for example, 1.7 m or less, for example, 1.6
m
or less). For example, the construction box may have a width of 0.7 m or more
(for example, 0.8 m or more, for example, 0.9 m or more, for example, 1.0 m or
more) and 1.3 m or less (for example, 1.2 m or less, for example, 1.1 m or
less).
zo For example, the construction box may have a height of 0.3 m or more
(for
example, 0.4 m or more, for example, 0.5 m or more) and 0.8 m or less (for
example, 0.7 m or less, for example, 0.6 m or less, for example, 0.5 m or
less).
The construction box may have, for example, respectively one or more
25 construction box side wall openings, for example in the form of one or
more
slots (for example, longitudinal slots), on one or more construction box side
walls, for example on each of the short construction box side walls, wherein
the
one or more construction box side wall openings may extend, for example,
vertically in an upward direction from a lower edge of the construction box
side
30 wall structure.
The construction box may, for example, comprise a holding structure (for
example, a construction platform holding structure) configured to hold the
construction platform in a lowermost position in the construction box. The
CA 03134375 2021- 10-20
17
holding structure may, for example, comprise or be at least co-formed by (for
example, be formed) a plate that is fixed to, for example, the construction
box
side wall structure (for example, to a lower end thereof) and against which
the
construction platform is supported when the construction platform is in a/the
5 lowermost position in the construction box. For example, the construction
platform may rest on the plate when the construction platform is in a/the
lowest
position in the construction box. For example, the plate may rest on the
construction box support member when the construction box is disposed on the
support structure. For example, the plate may have one or more openings (for
10 example, slots, for example, longitudinal slots) extending, for example,
inwardly
from an outer edge of the plate. The support structure may be configured, for
example, such that the construction platform (for example, an upper part or
upper portion of the construction platform, for example, a work surface of the
construction platform) is disposed in its lowermost position above the one or
15 more construction box side wall openings. The construction platform may,
for
example, have a thickness (for example, extension in the height direction or
vertical direction) equal to or greater than the length (and, respectively,
extension in the vertical direction and, respectively, in the height
direction) of
the construction box side wall openings. This may, for example, eliminate the
zo need for a complex device for closing the construction box side wall
openings.
The holding structure may, for example, have one or more protrusions or may
be at least co-formed (for example, be formed) by these, which protrusions
project, for example, inwardly from the side wall structure of the
construction
box, for example, from the short and/or the long construction box side walls
25 towards an opposite (construction box) side wall, and against which the
construction platform is supported when the construction platform is in a/the
lowermost position in the construction box.
For example, the construction box may be attachable to the support structure
30 such that the two short construction box side walls are each disposed
adjacent
to a portion of the support structure side wall structure (for example,
adjacent to
a respective support structure side wall, for example, adjacent to one of the
two
support structure side walls), for example respectively at a distance of 5 cm
or
less (for example, 3 cm or less, for example, 1 cm or less). The construction
CA 03134375 2021- 10-20
18
box may have, for example, at each of the short construction box side walls,
at
least one (for example, two) construction box side wall opening(s) configured
to
allow the support structures to extend therethrough when the construction box
is disposed on the support structure, such that the construction platform is
5 height-adjustable by vertical movement (and a movement in the height
direction, respectively) of the support structures, for example between a/the
lowermost position in which the construction platform is held by the holding
structure (for example the plate) and a/the uppermost position in which a
floor
(for example an upper part and an upper portion, respectively, for example a
10 work surface) of the construction platform is arranged substantially on
the same
height as anIthe upper edge of the construction box side wall structure (and
in
which the construction platform is arranged at the start of a/the 3D printing
process).
15 The construction box may, for example, be free of a drive means. The
construction box may, for example, have no active elements. For example, the
construction box may be formed without a drive and/or without active elements.
Thereby, the construction box may be constructed, for example, in a simple and
cost-effective way.
The construction box may, for example, comprise a heating device. The heating
device may be arranged, for example, on and/or in the construction platform.
The side wall structure of the construction box may be, for example, made of
ceramic, metal, for example, cast metal, stainless steel, or combinations
25 thereof. The construction platform may comprise, for example, a metal
floor, for
example a cast metal floor, or a stainless steel floor, or a ceramic floor.
Ceramic
material, for example, has good transmission of microwave radiation and is
therefore well suited for construction boxes that are to be subjected to a
microwave post process. The construction platform may for example comprise
30 an outlet device, for example comprising a perforated floor and a
closure
device, to remove particulate material from the construction box interior
space.
The construction box may comprise, for example, a construction box removal
device adapted to attach the construction box to and/or remove the
construction
CA 03134375 2021- 10-20
19
box from the support structure. The construction box removal device may be
arranged, for example, on the construction box side wall structure of the
construction box. The construction box removal device may be arranged on the
holding structure, for example the plate, for example under the plate, for
5 example on a side of the plate facing away from the construction box
interior
space. The construction box removal device may, for example, comprise at
least one (for example, two) forklift pockets in which a fork of a forklift
may
engage. This allows, for example, the construction box to be easily and
quickly
attached to and/or removed from the support structure and/or to be exchanged
10 easily and quickly.
The support structure may, for example, be configured to be microwave-
incompatible. A microwave-incompatible support structure is understood as
being a support structure that cannot be subjected to a post-process in a
15 microwave, for example because parts of the support structure, such as
the
drive, are damaged or destroyed in the process and/or because parts of the
support structure are made of a material that is not suitable for microwave
treatment. For example, the construction box may be configured to be
microwave-compatible. By a microwave-compatible construction box is meant a
zo construction box that can be subjected to a post-process in a microwave.
For
example, a drive-free construction box, i.e., a construction box without a
drive,
may be microwave-compatible.
For example, the construction platform may comprise a floor (for example, one
25 of the above-mentioned floors) and a floor support structure against
which the
floor is supported (for example, on which the floor rests). For example, the
floor
may comprise one or more (for example, two, for example, four) floor plates
that
may be, for example, surrounded (for example, enclosed) by a floor plate frame
structure. The floor support structure may have, for example, a honeycomb-
30 shaped structure. A honeycomb-shaped structure allows, for example, a
good
transmission of radiation (for example microwave radiation) and is therefore
well
suited for construction boxes that are to be subjected to a (microwave) post
process. Floor plates and/or floor plate frame structure and/or floor support
structure may be made of, for example, metal, for example cast metal,
stainless
CA 03134375 2021- 10-20
20
steel and/or ceramic. The construction platform may, for example, be
replaceably or interchangeably received within the side wall structure of the
construction box. For example, the construction platform may be removable
from the side wall structure of the construction box. For example, a
construction
5 platform removal device may be attachable to the construction platform
and
configured to remove the construction platform from the side wall structure of
the construction box. For example, the construction platform may be configured
such that a construction platform removal device is attachable to the
construction platform. The construction platform removal device may, for
10 example, comprise or be at least co-formed (for example be formed) by
several
(for example, four) eyebolts, each of which may be screwed into a thread (for
example, internal thread) provided on the construction platform.
The construction box system may, for example, comprise one or more further
15 construction boxes, which may, for example, each be exchangeable for the
(first) construction box and attached to the support structure. The one or
more
further construction boxes may, for example, be formed as described above.
The one or more further construction boxes may, for example, be formed like
the first construction box or may be different from the first construction
box.
The construction box system may, for example, comprise one or more further
construction platforms, each of which may, for example, each be exchangeable
for the (first) construction platform and receivable in the side wall
structure of
the construction box. The one or more further construction platforms may, for
25 example, be formed as described above. The one or more further
construction
platforms may, for example, be formed like the first construction platform or
be
different from the first construction platform.
The construction box system may, for example, comprise a rail system or roller
30 system along which the support structure with the construction box
attached to
it can be moved, for example by means of its own travel drive integrated in
the
support structure. The rail system or roller system may, for example, be
configured as described above.
CA 03134375 2021- 10-20
21
The construction box system may, for example, comprise a control device
configured, for example, to control the lift drive and/or the travel drive
and/or the
heating device and/or the outlet device. The control device may comprise, for
example, a/the central control device of the 3D printer (first control device)
5 and/or a/the control device integrated into or arranged on the support
structure
(second control device), wherein, for example, the control device integrated
into
or arranged on the support structure (second control device) may be configured
to control the lift drive and/or the travel drive and/or the heating device
and/or
the outlet device, wherein for example the central control device (first
control
10 device) may be configured to control a coater (for example coater for
application
in layers of particulate material to the construction platform) and/or a print
head
(for example print head for selective printing of the particulate material by
binder
jetting method), and wherein for example the central control device (first
control
device) may be connected to the control device (second control device)
15 integrated in the support structure.
According to various aspects of the invention, a 3D printer has a construction
box system which may be formed, for example, as described above, and a
coater for application of particulate material in layers onto the construction
zo platform and/or a print head for selective printing of the particulate
material
using a binder jetting method.
According to various aspects of the invention, a 3D printer system has a 3D
printer, which may be formed, for example, as described above, and, for
25 example, one or more selected from an unpacking station for unpacking
the
built components from the construction box and a microwave device and/or an
oven, in which the construction box is receivable, for curing and/or drying
the
component disposed in the construction box.
30 According to various aspects of the invention, the above-described
construction
box system, the above-described 3D printer, and/or the above-described 3D
printer system may be used for 3D printing of casting molds and/or casting
cores and/or for application of particulate material in layers onto the
CA 03134375 2021- 10-20
22
construction platform and selective printing of the particulate material using
a
binder jetting method.
According to various aspects of the invention, a 3D printing method includes
the
5 steps:
providing a construction box system, which may for example be formed
as described above, wherein the construction box is attached to the support
structure,
building a component by 3D printing in the construction box interior
10 space of the construction box,
removing the construction box from the support structure, for example in
an automated manner, and
supplying the removed construction box to a post process, such as
unpacking the built components from the removed construction
15 box, for example in an unpacking station, and/or
curing and/or drying the built components in the removed
construction box, for example in a microwave device and/or an oven,
and/or
attaching a construction box to the support structure, for example
zo reattaching the same construction box after the built components have
been
unpacked, or attaching a different construction box (changing the construction
box), optionally followed by rebuilding a component by 3D printing in the
construction box interior space of the construction box.

a construction box 30 of a construction box system 10 for a 3D printer 12, for
example in a construction box 30 of a construction box system 10 according to
the first, second or third embodiments. Figures 19 and 20 show perspective
views of a 3D printer.
As shown in the Figures, a construction box system 10 for a 3D printer 12
according to the embodiments has a construction box 30 having a side wall
structure 32 and a construction platform 34 received within the side wall
structure 32, the side wall structure 32 defining an upwardly open
construction
15 box interior space 36 for building a component in 30 printing,
downwardly
limited by the construction platform 34, and a support structure 50 having its
own drive 52 integrated into the support structure 50 and to which the
construction box 30 is releasably attachable so that the construction box 30
can
be repeatedly removed from the support structure 50 and subsequently
zo reattached to the support structure 50 after building the component in
the
construction box interior space 36.
As shown, for example, in Figures 2 to 5, 13 and 14, the drive 52 integrated
into
the support structure 50 may comprise, for example, a lift drive 54 for
adjusting
25 the height of the construction platform 34, which is configured to
adjust the
construction platform 34 of the construction box 30 in height when the
construction box 30 is attached to the support structure 50.
The lift drive 54 may be formed by, for example, two electric motors
30 synchronized with each other, each having a vertical drive axis. The
lift drive 54
(for example, each of the two electric motors) may be configured to drive a
spindle drive 80, for example. The/each spindle drive 80 may, for example,
comprise a rotatable screw spindle 82 having a vertical axis of rotation and a
CA 03134375 2021- 10-20
27
spindle nut 84. The screw spindle 82 may, for example, be connected to the
lift
drive 54, for example via a belt or a chain.
As shown, for example, in Figures 2, 3 and 14, the drive 52 integrated into
the
5 support structure 50 may comprise, for example, a travel drive 56 for
moving
the support structure 50, which is arranged to move the construction box
system 10 between a first position, in which the construction box system 10 is
arranged to build the component in the 3D printer 12, and a second position in
which the construction box system 10 is arranged, for example, outside the 3D
10 printer 12, for example along a rail system 14 or a roller system
extending
between the first and second positions (see, for example, Figures 19 and 20).
The travel drive 56 may be formed, for example, by an electric motor having a
vertical drive axis. The travel drive 56 (for example, the electric motor) may
be
15 configured, for example, to drive a gear wheel 90 fixed to the support
structure
50. The gear wheel 90 may, for example, be connected to the travel drive 56.
The gear 90 may, for example, be attached to the lower side of the support
structure 50 and/or may have a horizontal wheel plane and/or be a horizontal
gear wheel. The gear wheel 90 fixed to the support structure 50 may, for
20 example, be configured to cooperate with a rack, for which purpose the
gear
wheel 90 may, for example, be configured to engage and roll on the rack when
driven by the travel drive 56, such that the construction box system 10 is
movable along the rack.
25 For example, as shown in Figures 2 to 5, 13 and 14, the lift drive 54
and/or the
spindle drive 80 and/or the travel drive 56 may be disposed, for example, in a
space formed between a support structure side wall 58a, 58b and a cladding
wall 86a, 86b. The lift drive 54 and/or the spindle drive 80 and/or the travel
drive
56 may, for example, be arranged adjacent to the support structure side wall
30 58a, 58b, for example, on a side of the support structure side wall 58a,
58b
facing away from the construction box 30.
The lift drive 54 and/or the travel drive 56 may, for example, be arranged
outside the side wall structure 32 of the construction box 30 when the
CA 03134375 2021- 10-20
28
construction box 30 is attached to the support structure 50, for example, in a
plan view of the construction box system 10 next to the construction box 30
adjacent to the side wall structure 32 of the construction box 30 and/or
adjacent
to at least one/the side wall 58a, 58b of the support structure 50, for
example in
5 the case of an elongated construction box 30 in a longitudinal direction
in front
of and/or behind the side wall structure 32 of the construction box 30 and/or
in
front of and/or behind at least one/the side wall 58a, 58b of the support
structure 50.
10 The support structure 50 may be formed to be elongated, for example, and
the
lift drive 54 and/or the travel drive 56 may be disposed, for example, at at
least
one longitudinal end of the support structure 50.
As shown, for example, in Figures 12 and 15, the construction platform 34 may,
15 for example, be engaged from below by one or more support structures 70,
for
example one or more support arms 72, in communication with and drivable by
the lift drive 54 when the construction box 30 is attached to the support
structure 50, wherein optionally one or more slots 74, 78 are formed in the
side
wall structure 32 of the construction box 30 and/or in a support structure
side
zo wall structure 58, through which the one or more support structures 70
extend.
As shown, for example, in Figure 5, the support structure 70 may, for example,
be connected to the spindle nut 84, for example, via a support structure
fastening member 88 to which the support structure 70 is fastened and which is
25 connected to the spindle nut 84.
The support structure 50 may comprise, for example, a support structure side
wall structure 58 that surrounds the side wall structure 32 of the
construction
box 30 in a circumferential direction at least in sections, for example,
surrounds
30 it on both end faces of an elongated construction box 30.
The support structure side wall structure 58 may surround the side wall
structure 32 of the construction box 30, for example, in a circumferential
direction in sections, thereby forming a recess 60, the recess 60 being
CA 03134375 2021- 10-20
29
dimensioned, for example, such that the construction box 30 may be laterally
removed from the support structure 50 and/or reattached to the support
structure 50 through the recess 60. The support structure side wall structure
58
may comprise, for example, two opposing recesses 60, each dimensioned, for
5 example, such that the construction box 30 may be laterally removed from
the
support structure 50 and/or reattached to the support structure 50 through the
respective recess 60. The at least one recess 60 may, for example, extend
along a long side of the side wall structure 32 of the construction box 30.
10 For example, as shown in Figures 1, 2, 11, 12, and 15, the construction
box 30
may, for example, be supported by the support structure 50 such that an upper
edge of the side wall structure 32 of the construction box 30 is disposed
substantially at the same height as an upper edge of the support structure
side
wall structure 58 when the support structure 50 is disposed on the
construction
15 box 30.
For example, the support structure 50 may comprise at least one construction
box support member 108 for supporting the construction box 30 when the
construction box 30 is disposed on the support structure 50. For example, the
zo construction box support member 108 may be disposed on the support
structure side wall structure 58. For example, the support structure 50 may
comprise two opposing construction box support members 108. The one or
more support structures 70 may have, for example, a lower height (for example,
a lower extension in a vertical direction) than the construction box support
25 members 108 when the support structures 70 are in their lowermost
position
(see, for example, Figures 13 to 15).
For example, the construction box 30 may have a rectangular shape in a plan
view, with two opposing short construction box side walls 32b, 32d and two
30 opposing long construction box side walls 32a, 32c.
For example, as shown in Figures 6, 8, and 16, the construction box 30 may
have, for example, on one or more construction box side walls 32a, 32b, 32c,
32d, for example on each of the short construction box side walls 32b, 32d,

respectively one or more construction box side wall openings 76, for example
in
the form of one or more slots 78, the one or more construction box side wall
openings 76 extending, for example, from a lower edge of the construction box
side wall structure 32 vertically in an upward direction.
The construction box 30 may comprise, for example, a holding structure 38
configured to hold the construction platform 34 in a lowermost position in the
construction box 30. For example, as shown in Figures 6 to 8 and 16, the
holding structure 38 may, for example, comprise a plate 40 disposed on the
construction box side wall structure 32. For example, the holding structure 38
(for example, the plate 40) may be configured such that the construction
platform 34 (for example, an upper region of the construction platform 34) is
disposed in its lowermost position above the one or more construction box side
wall openings 76 (see, for example, Figures 7 and 8).
For example, the construction box 30 may comprise a construction box removal
device 104 configured to attach the construction box 30 to the support
structure
50 and/or to remove it from from the support structure 50. For example, the
construction box removal device 104 may be disposed on the construction box
zo side wall structure 32 of the construction box 30. The
construction box removal
device 104 may be disposed, for example, on the plate 40, for example, under
the plate 40, for example, on a side of the plate 40 facing away from the
construction box interior space 36. The construction box removal device 104
may comprise, for example, two forklift pockets 106 into which the fork of a
forklift may engage and which are configured, respectively, to be engaged by
the fork of a forklift.
The support structure 50 may be, for example, microwave-incompatible and/or
the construction box 30 may be, for example, microwave-compatible. The
construction box 30 may, for example, be free of a drive means and/or have no
active elements. The side wall structure 32 of the construction box 30 may be,
for example, made of ceramic, metal, for example, cast metal, stainless steel,
or
combinations thereof.

The construction platform 34 may comprise, for example, a metal floor, for
example a cast metal floor, or a stainless steel floor, or a ceramic floor. A
heating device may be disposed on and/or in the construction platform 34, for
example. The construction platform 34 may comprise, for example, an outlet
5 device, for example comprising a perforated floor and a closure device,
to
remove particulate material from the construction box interior space 36.
As shown, for example, in Figures 9, 101 17, and 18, the construction platform
34 may comprise, for example, a floor 94 and a floor support structure 96
10 against which the floor 94 is supported. The floor 94 may comprise, for
example, one or more floor plates 98 that may be enclosed by, for example, a
floor plate frame structure 100. The floor support structure 96 may have, for
example, a honeycomb-shaped structure. Floor plates 98 and/or floor plate
frame structure 100 and/or floor support structure 96 may be made of metal,
for
15 example, cast metal, stainless steel, and/or ceramic. A construction
platform
removal device 102 may be attachable to the construction platform 34, for
example, configured to remove the construction platform 34 from the side wall
structure 32 of the construction box 30 (for example, in Figure 18, the
construction platform removal device 102 is formed by four eyebolts screwable
zo into a thread provided on the construction platform 34; prior to a 30
printing
process, the eyebolts must be removed from the construction platform 34).
The construction box system 10 may, for example, comprise one or more
further construction boxes 30 each exchangeable for the first construction box
25 30 and attachable to the support structure 50, wherein the one or more
further
